PERMASTORE
has been a world leader in the design and supply of specialist
roofed vessels for anaerobic digesters since the 1970s.
It has developed considerable expertise in designing the optimum
configuration to meet the exacting requirements of major international
process companies, contractors and operators. It understands
the issues related to the variations in influent waste streams;
the needs of different digestion processes (mesophilic or
thermophilic); the problems of maintaining consistent operating
pH levels and temperatures; the essential requirement for
structural integrity to eliminate oxygen ingress; the requirement
to satisfy the various structural loadings from suspended
internal mixing equipment, as well as the normal external
loadings of wind, snow etc. Above all it understands that
structures may need to be adapted during their lifetime as
waste materials change and process technology advances. By
addressing the differing needs of the liquid and gaseous zones,
modular Glass-Fused-to-Steel offers a unique opportunity to
combine the optimum materials with future flexibility and
provide insulated  vessels
with considerable structural integrity and proven long economic
life.
As
a result of the considerable experience in this sector, PERMASTORE
has enjoyed repeat business from customers who have learned
from their own experience how much their own risks have been
reduced. PERMASTORE® digesters have operated
in conditions that have resulted in the
demolition of concrete structures unable to withstand the corrosive
nature of the materials and processes. |
